The Manual Release Tool (MRT) is intended for use when oxygen masks fail to deploy during which event?

The Manual Release Tool is used when the cabin loses pressure and oxygen masks fail to deploy automatically. In a decompression, masks are meant to drop so passengers can breathe, and the MRT allows the crew to manually release the masks if the automatic system doesn’t work. The other scenarios—fire outbreaks, landing gear problems, or medical emergencies—do not hinge on manually releasing oxygen masks, so they aren’t the situation MRT is intended for.
